Description

Technical Field

[0001] The utility model belongs to the technical field of biological testing equipment, and in particular relates to a fluorescence polarization instrument used for brucellosis detection. Background Art

[0002] The fluorescence polarimeter for brucellosis detection uses a unique fluorescence polarization detection principle to measure the rotation time of polarized light to detect antibodies in serum, and determines the positive or negative result based on the mp reading displayed by the FPA detector. The fluorescence polarization assay is a uniform detection method that does not require a washing step or removal of unreacted components. It is used for epidemiological surveys and on-site testing for epidemic response, and for rapid testing of suspected cases in clinical laboratories and disease control laboratories. It can detect all Brucella antibodies in human serum, including all types of antibodies such as IgG1, IgG2, IgG3, IgG4, IgM, IgA, and IgD.

[0003] The prior art discloses a fluorescence polarimeter for brucellosis detection with patent announcement number CN217981251U, which comprises a chassis, a socket is arranged on the left side of the chassis, a sample door is arranged on the front side of the chassis through a chain, a support rod and a claw extending to the outside of the sample door are installed inside the sample door through a driving mechanism, a steel wire rope is arranged at the bottom of the driving mechanism, an iron block fixedly connected to the steel wire seam is slidably installed inside the sample door, an electromagnet located at the bottom of the iron block is arranged inside the sample door, an installation cavity is opened inside the sample door, and the hinge comprises an insulating shaft, a bearing, an insulating ring, an inner conductive sheet and an outer conductive sheet. The fluorescence polarimeter for brucellosis detection has the advantage of convenient swab installation, which solves the problem that the swab needs to be manually placed in the instrument, the device for fixing the swab has a simple structure, requires two-handed operation, and is easily unstable in fixation. However, the following deficiencies still exist in actual use: From a practical point of view, the swab is clamped by rotating the sample door when it is placed in the instrument.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-5 The utility model provides a fluorescence polarimeter for brucellosis detection, including a chassis 1, a socket 101 is arranged on the left side of the chassis 1, a sample door 2 is arranged on the front side of the chassis 1, a control switch 201 is fixedly installed on the front side of the sample door 2, a limiting mechanism 3 is arranged on the upper part of the sample door 2 on the chassis 1 and is connected through the limiting mechanism 3, a clamping device 5 is fixedly installed on the inner side of the sample door 2, and a pushing mechanism 4 is arranged between the sample door 2 and the chassis 1.

[0024] The clamping device 5 has been specifically disclosed in the patent announcement number CN217981251U, and will not be elaborated on here. The limiting mechanism 3 can facilitate the sample door 2 to be stably connected to the chassis 1, and it can be quickly released to facilitate the opening and closing of the sample door 2. It cooperates with the pushing mechanism 4 to ensure the stability of the opening and closing of the sample door 2, improve the stability of the swab, and facilitate detection.

[0025] Further as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth explaining in detail that the limiting mechanism 3 includes a positioning port 303, the positioning port 303 is opened on the chassis 1, and a connecting plate 304 is fixedly connected to the chassis 1 on the rear side of the positioning port 303, a pin block 301 is arranged in the positioning port 303, and fixed shafts 306 are fixedly connected on both sides of the pin block 301. The positioning port 303 is rotatably connected to the pin block 301 through the fixed shaft 306, and a spring 305 is fixedly installed at the bottom of the connecting plate 304 and is connected to the pin block 301. The front side of the positioning port 303 corresponds to a clamping block 302 fixedly connected to the sample door 2, the positioning port 303 is set through the upper and front parts of the chassis 1, the clamping block 302 is matched with the positioning port 303, and the pin block 301 is a special-shaped setting, which is formed by integral processing.

[0026] Pressing the pin block 301 causes the pin block 301 to rotate in the positioning port 303 via the fixed shaft 306, thereby disengaging the pin block 301 and the clamping block 302, releasing the clamping of the sample door 2. At the same time, the pin block 301 is squeezed by the elastic force of the spring 305 to ensure the stability of the clamping process.

[0027] According to the above working process, it can be known that: through the setting of the limiting mechanism 3, when the swab is placed on the sample door 2 and clamped by the clamping device 5 and then sent into the chassis 1 for detection, the sample door 2 can be stably and quickly installed on the chassis 1, thereby improving the stability between the two, ensuring the stability of the swab on the sample door 2 during the detection process, and improving the detection efficiency.

[0028] Further as Figure 2 and Figure 3 As shown, it is worth specifically explaining that the pushing mechanism 4 includes a mounting groove 407, which is opened at the bottom of the sample door 2, and a motor 404 is fixedly installed in the mounting groove 407. A screw rod 401 is fixedly connected to the output end of the motor 404, and sliding rods 402 are fixedly connected to the surface of the sample door 2 on the left and right sides of the screw rod 401. The screw rod 401 corresponds to a matching threaded groove 405 opened on the chassis 1, and a limiting plate 403 is fixedly connected to the top of the inner side of the sample door 2 above the sliding rod 402, and the limiting plate 403 corresponds to a sliding groove 406 opened on the chassis 1. The sliding rod 402 corresponds to a matching limiting hole opened on the chassis 1 and slides inside. The limiting plate 403 slides in the chassis 1 through the sliding groove 406, and the motor 404 is electrically connected to the control switch 201.

[0029] The motor 404 is controlled by the control switch 201, and the screw rod 401 is rotated to make the sample door 2 slide and be pushed out on the chassis 1 through the slide bar 402 and the limit plate 403, so that the sample door 2 is opened and closed, and runs stably at the same time to ensure the stability of the swab.

[0030] This solution has the following working process: when this device is used, when it is necessary to open the sample door 2 to place a swab, the pin block 301 is pressed at this time, so that the pin block 301 rotates in the positioning port 303 through the fixed shaft 306, so that the pin block 301 and the clamping block 302 are disengaged. At this time, the motor 404 is controlled to run by the control switch 201, and the sample door 2 slides and is pushed out on the chassis 1 through the sliding rod 402 and the limit plate 403 through the rotation of the screw rod 401, so that it is convenient to clamp the swab on the sample door 2 through the clamping device 5. After the installation is completed, the motor 404 is controlled to run in the reverse direction by the control switch 201, so that the sample door 2 is rotated and pushed into the chassis 1 through the screw rod 401 and closed on the chassis 1. At this time, the sample door 2 is fixedly installed on the chassis 1 through the clamping connection between the clamping block 302 and the pin block 301, and the pin block 301 is squeezed by the elastic force of the spring 305 to ensure the stability of the clamping process.

[0031] In summary: through the setting of the limiting mechanism 3, when the swab is placed on the sample door 2 and clamped by the clamping device 5 and then sent into the chassis 1 for detection, the sample door 2 can be stably and quickly installed on the chassis 1, thereby improving the stability between the two, ensuring the stability of the swab on the sample door 2 during the detection process, and improving the detection efficiency; through the setting of the pushing mechanism 4, the sample door 2 can be pushed and operated smoothly on the chassis 1, so that the swab can be clamped and removed conveniently, which is convenient for detection, improves the stability of the swab clamping, prevents the swab from overflowing, facilitates detection, and improves the practicability of the device.
